Short description of error
Assert going to Texture Paint workspace without a UVMap

Exact steps for others to reproduce the error
From the default startup file:

  • remove the UVMap from the default Cube
  • switch to Texture Paint workspace -->
BLI_assert failed: /blender/source/blender/draw/intern/draw_cache_impl_mesh.c:1147, drw_mesh_batch_cache_check_available(), at '!DRW_batch_requested(((GPUBatch **)&cache->batch)[i], 0)'

Sound rather harmless, just dropping this here so @Jeroen Bakker (jbakker) is aware.

This needs to be investigated, IMO it should still create a batch, but it should have an empty IndexBuffer. It could be that the current implementation doesn't following the architecture. The draw manger used to have some hacks in order to support rendering UVs in the old image editor. The new image editor should work fully in the architecture. That was one of the goals of that change.
